abstract= A Gram-negative, non-motile, rod-shaped bacterial strain, designated MA1-6T, was isolated from a sea squirt (Halocynthia roretzi) collected from the South Sea, Korea, and was characterized to determine its taxonomic position. Strain MA1-6T grew optimally at pH 7.0–8.0, at 30 °C and in the presence of 2–3 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain MA1-6T fell within the clade comprising Ruegeria species and exhibited 95.3–96.5 % similarity to the type strains of recognized Ruegeria species. Strain MA1-6T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the major fatty acid, which is consistent with data for Ruegeria species. The major polar lipids detected in strain MA1-6T and Ruegeria atlantica KCTC 12424T were phosphatidylcholine, phosphatidylglycerol, an unidentified aminolipid and an unidentified lipid. The DNA G+C content of strain MA1-6T was 58.6 mol%. Differential phenotypic properties, together with phylogenetic distinctiveness, demonstrated that strain MA1-6T can be distinguished from recognized Ruegeria species. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain MA1-6T is considered to represent a novel species of the genus Ruegeria , for which the name Ruegeria halocynthiae sp. nov. is proposed; the type strain is MA1-6T ( = KCTC 23463T = CCUG 60744T).,
